Use of RECYCLED AGGREGATES In CONCRETE- A Paradigm Shift

The concrete debris were collected from different (four) sources with the age ranging from 2 to 40 years old and broken into the pieces of approximately 80 mm size with the help of hammer & drilling machine. The foreign matters were sorted out from the pieces. Further, those pieces were crushed in a lab jaw crusher and mechanically sieved

How to Recycle Concrete Blocks | Hunker

Recycling materials whenever possible keeps waste out of landfills and takes no more effort than disposing of the waste. Old concrete blocks, which include cinder blocks and pavers, can be crushed, and the material can be used for filler in Portland cement. Homeowners with concrete blocks have a couple of different recycling options to choose from.
